Chandra Seetharaman 6c10db72c9 [SCSI] scsi_dh: Reference count scsi_dh_attach 
Problem reported: http://marc.info/?l=dm-devel&m=124585978305866&w=2

scsi_dh does not do a refernce count for attach/detach, and this affects
the way it is supposed to work with multipath when a device is not
in the dev_list of the hardware handler.

This patch adds a reference count that counts each attach.
